The invention relates to a cop winding machine having a winding spindle which both rotates and reciprocates.

I-Ieretofore with cop winding machines of this kind the thread guide and its carrier remained stationary relatively to the reciprocating `spindle during the formation of the pirn and was only thrust back to the left, in accordance with the application of the material onto a guide bar by means of a cone ring anda ball lock or by means of a feeler plate.

The cop winding machine according to the invention is characterized by the thread guide having imparted to "itan additional movement relatively to the reciprocating movement of the spindle, so that the successive layers of thread at the peak of the winding cone are axially off-set with krelation to each other. This displacement of location of the winding provides a rmerbinding of the layers of thread at the peak of the cop. p

Two constructional examples of the invention are shown in the drawing, in which:

Fig. 1 is a vertical section and (Fig. 1) of one iirst example.

Figs. 3 and 4 are developments, and

Fig. 5 is a vertical section of a second constructional form.

1 designates the spool spindle, 2 thecam` groove disc serving to reciprocate thelatter and having a lift 7a, and 4 isthe driving pulley which'rotates kthe spindle and is connected to the spindle 1 is known manner so as not to Vobstruct thesliding of the spindle.` 3 designates the thread guide carried by the support 5 and thrust back, by means of the usual cone ring 6 and ball lock v7, against the feeler rod 8, in accordance with the application of the materialto the cop. A-feeler plate of knownkind may be employed'in lieu of the cone ring 6.

The following device serves to effect thev axial displacement of the layers of threadl at the peakof the winding cone.

The shaft 9 of thecamdisc is provided with a toothed part 10 which engages with a toothed part 11a on a pin 11. c The front` face of this toothed part 11a is providedwith four cams 12, the development of which is shown roller 13 Fig. 2 a cross section on the line II--II @plate 6a as is usual with pirn ma -inV Fig. 3@ These cams 12 are of different The feeler bar 8 which carries a and is under the inliuence of a `spring 14 has imparted to it by theV cam 1.2 '55 hei ghts.v

a reciprocating movement corresponding to the height of the cams 12. This reciprocating movementofgthe bar 8 is socalculated that its extreme left hand position coincides with the extreme right hand position-ofthe 30 spindle, so that the development of four successive thread layers may bey illustrated by the diagrams as shown in Fig. 4.

ThisV figure shows that the height of theA y cams 12 is such that the additional movement i.

of the thread guide?) produces firstly a progressivelength of stroke (frompoint III to point I), whereupon the following thread layers-have al correspondingshortening of stroke (from point I to point III). It should also be mentioned that this lengthening of the stroke g only takes place yat the peak Vof the windingcone, whileV there is no displacement* ofthe stroke at theaxially opposite Vpoint ,Y

of reversal of the thread.y

In the example according to Fig. 5 a kfeeler chines, is used inl lieu of the cone ring 6. I claim:
